Mathias Mohl looks at creating and animating a Hand-Drawn Half Pipe animation in After Effects that shows off the usage and workflow for his iExpressions Scripting tool. iExpressions allow you to use After Effects expressions without writing or reading a single line of code. It ships with over 85 iExpressions in seven different categories – and each of them comes with an easy and intuitive to use interface. As its such a huge package, it is difficult to explain all its possibilities in a few lines. Check out the iExpression Script Workflow in After Effects here.

from the tutorial description: In this three part tutorial series you will learn animation techniques that go beyond the usual keyframing. You can make your animations more believable and realistic using real physics simulations! WithiExpressions this can be done easy and quickly without writing a single line of expressions code. In the first part we create all the basic ingredients using the pen tool. We also cover a clever technique to smooth your pen strokes.
